Modeling of the deformation impact of the main structure framework on the stress and strain state of its individual parts

Abstract

The paper presents the calculation of the metal frame of the stairwell under the action of static loads, which was performed using the Dlubal RFEM application software package. The computer modeling technique for the study of metal structures in this software environment was adapted in accordance with building regulations. The general stress calculation in software for the finite element analysis was performed and the selected sections were checked in the RF-STEEL EC3 calculation module for two groups of limit states. Various options for calculating a stairwell made of a metal frame are analyzed. The influence of deformations of the main framework of the structure on the stress-strain state of its individual part was evaluated using software.
